China playing with their currency is getting the rest of the world rather upset. It keeps their products low in price, and no one else's. But it is one of the last bastions of control the Party has, so it won't float, and they won't adjust until they absolutely have to. Really, what's happening is the dollar is falling against all currencies...except the one it really needs to fall against.
And until the cork pops and China does a re-adjustment (IF they do a reasonable one), I predict the dollar will continue to fall. This will make U.S. made goods less expensive, but makes imported materials and everyone else's products expensive - worst of all will be oil because its denominated in dollars and sold by countries who don't want to be paid in falling dollars.
BTW, China is throwing money at manufacturing to keep people working - can you say oversupply? So companies that have no business staying in business just continue on the dole - and unlike GM these aren't loans - which means no incentive to actually make their products competitive. So quality is going down.
